Constructor Detail

ScriptedJobClass

public ScriptedJobClass()

Creates a new instance of this job thread. This constructor does not need to do anything other than invoke the constructor for the superclass.

Method Detail

getJobName

public java.lang.String getJobName()

Returns the user-friendly name that is to be used for this job class in the administrative interface.

Specified by:

getJobName in class JobClass

Returns:

The user-friendly name for this job class.

getJobDescription

public java.lang.String getJobDescription()

Returns a description of this job that can be seen in the administrative interface.

Specified by:

getJobDescription in class JobClass

Returns:

A description of this job class.

getJobCategoryName

public java.lang.String getJobCategoryName()

Retrieves the name of the category in which this job class exists. This is used to help arrange the job classes in the administrative interface.

Overrides:

getJobCategoryName in class JobClass

Returns:

The name of the category in which this job class exists.

getParameterStubs

public ParameterList getParameterStubs()

Returns the set of parameters whose value may be specified by the end user.

Specified by:

getParameterStubs in class JobClass

Returns:

The set of configurable parameters for this job class.

getStatTrackerStubs

public StatTracker[] getStatTrackerStubs(java.lang.String clientID,
                                         java.lang.String threadID,
                                         int collectionInterval)

Retrieves the set of stat trackers that will be maintained by this job class. The stat trackers returned by this method do not have to actually contain any statistics -- the display name and stat tracker class should be the only information that callers of this method should rely upon. Note that this list can be different from the list of statistics actually collected by the job in some cases (e.g., if the job may not return all the stat trackers it advertises in all cases, or if the job may return stat trackers that it did not advertise), but it is a possibility that only the stat trackers returned by this method will be accessible for some features in the SLAMD server.

Specified by:

getStatTrackerStubs in class JobClass

Parameters:

clientID - The client ID that should be used for the returned stat trackers.

threadID - The thread ID that should be used for the returned stat trackers.

collectionInterval - The collection interval that should be used for the returned stat trackers.

Returns:

The set of stat trackers that will be maintained by this job class.

getStatTrackers

public StatTracker[] getStatTrackers()

Retrieves the set of stat trackers that are maintained by this job class.

Specified by:

getStatTrackers in class JobClass

Returns:

The set of stat trackers for this job class.

validateJobInfo

public void validateJobInfo(int numClients,
                            int threadsPerClient,
                            int threadStartupDelay,
                            java.util.Date startTime,
                            java.util.Date stopTime,
                            int duration,
                            int collectionInterval,

Overrides:

initializeClient in class JobClass

Parameters:

clientID - The ID assigned to the client running this job.

parameters - The set of parameters provided to this job that can be used to customize its behavior.

Throws:

UnableToRunException - If the client initialization could not be completed successfully and the job is unable to run.
